We add a return code to wait_for_bb() to be able to report errors to the

Added posted writes (read after writes) to effect the
change immediately for channel confiuration and channel
enable register
Disable the channel to purge receieve data in TX_ONLY
mode transfer otherwise rx data will get affected by
the next immediate RX_ONLY mode transfer
Wait for the EOT bit to be set after last byte has been
loaded to TX shift register in the the TX_ONLY mode.This
ensures TX data has been completely shifted out
Disable the channel in RX_ONLY mode before reading the
last data from RXX register to prevent the SPI slave
to transmit next word

Instead of passing individual registers by value to board_get_mem_timings,
pass a board_mem_timings structure pointer for the board files to fill in.
Pass same structure pointer to write_sdrc_timings. This saves about

The ext4write code has been using direct calls to 64-32 division
(/ and %).
Officially supported u-boot toolchains (eldk-5.[12].x) generate calls
to __aeabi_uldivmod(), which is niether defined in the toolchain libs
nor u-boot source tree.
Due to that, when the ext4write command has been executed, "undefined
instruction" execption was generated (since the __aeabi_uldivmod()
is not provided).
To fix this error, lldiv() for division and do_div() for modulo have
been used.
Those two functions are recommended for performing 64-32 bit number
division in u-boot.
